SELK achieved its first business success through the production of electronic quartz clocks, LEDs, and microwave filters. Since 1992 it is today one of the most modern backend production companies of electro-ceramic components.

Since 1976, when it has been established, to date, our core business has changed according to trends on Croatian and foreign markets and models of business cooperation with partners.

SELK’s success and pride are that, after privatization, the number of employees has increased 10 times over the last 24 years.
